I thinned out the Cc list and left over only maintainers and major
contributors to the code.

Phillip and me are kind of git magicians. We can make code disappear during
rebase :-) The piece of code was part of a commit, but it never made it into
the final patch file.

I hope, there are no major issues with our patch set.

This patch set fixes several checkpatch warnings in tty/serial/8250.

Patch 1/15: Adds missing spaces (mainly to function/macro headers)
Patch 2/15: Replace spaces with tabs wherever possible
Patch 3/15: Slight patch which moves an opening curly brace
Patch 4/15: Fixes multiline comment style
Patch 5/15: Removes else blocks after return statements
Patch 6/15: Slight patch which moves EXPORT_SYMBOL macro to correct
Patch 7/15: Slight patch which removes an unneccessary line continuation
Patch 8/15: Slight patch which adds parentheses to a macro definition
Patch 9/15: Merges user-visible multiline strings to a single line
Patch 10/15: Replace printk by dev_* or pr_* where appropriate
Patch 11/15: Remove orphaned debug macro
Patch 12/15: Fix warnings in dev_dbg by adding two casts
Patch 13/15: Fixes code indentation
Patch 14/15: Add a generic port macro
Patch 15/15: Refactor a switch/case statement

Remaining checkpatch warnings after applying this patch series:

-line over 80 characters
This error mostly occurs in serial_cs.c, which contains long-lined
macro calls. However, splitting these calls into multiple lines would
not increase readability.

-externs should be avoided in .c files
This occurs in 8250_hp300.c. There is no corresponding header file
the extern statement could be moved to. It could be moved to 8250.h
but this would affect other .c files.

-Use #include <linux/*.h> instead of <asm/*.h>
This warning has been left open for more experienced kernel hackers.
This patch series is about style issues. We do not intend to alter
the code behavior.
-struct uart_ops should normally be const
This warning only occurs in 8250_core.c. The corresponding struct
cannot be declared as const because it is altered in
serial8250_isa_init_ports(). Maybe a checkpatch exception should
be added for this particular warning.

-quoted string split across lines
These strings were ignored because they otherwise would exceed
80 characters in a single line. These particular strings use
format specifiers, which break the ability to grep for them anyway.
